Plankton is instrumental in the aquatic ecosystem, plankton can be an indicator of fertility and pollution. The quality of a water especially the flooded waters can be determined based on the fluctuations of the plankton population that will affect the trophic levels of the waters. The quality of a water can be measured by knowing the value of the Saprobic Index (SI). The Saprobic index is an index that closely relates to the pollution level. This research aims to determine the level of fertility and pollution levels in the waters of Telaga Tunjung Dam, based on the status of Trophic and Saprobic's structure of Phytoplankton, knowing the relationship (linkage) of trophic status and structure Saprobic phytoplankton with variable water quality in Telaga Tunjung Dam. The methods of study used are descriptive methods of case study. The research was conducted on five stations with four repetitions. Plankton sampling performed actively using plankton net with mesh size 60 μm diameter 25 cm. Based on the results of the status of the trophic waters in Telaga Tunjung Dam is at the head of high Water Fertility (Eutrofik). The pollution level is mild to moderate water with a saprobic index from 0,739 to -0,583. The trophic level relationship and the saprobic structure with the water quality variable show that good water quality affects the abundance of high phytoplankton and mild to moderate pollution levels.

Snakehead fish (Channa striata) is a freshwater fishery commodity in Indonesia which has a high protein content. Many studies on the benefits of snakehead fish have resulted in an increase in the amount of demand for these fish. One of the production factors that support fish farming is feed. The snakehead fish seeds have an average length of 2 cm, with rudimentary digestive organs. Therefore, the most suitable feed as seed feed is natural food. Commonly used natural feed is water fleas (Daphnia sp.) and silk worms (Tubifex sp.). This study aims to determine the effect of a combination of feed on the growth of snakehead fish seeds and to determine the combination of feed that gives the highest growth in snakehead fish seeds. This research was conducted at the Fisheries Resources Development Laboratory, Warmadewa University for 60 days, from March to April 2020. The method used in this study was an experimental study using a completely randomized design (CRD) with six treatments and three replications. The analysis used in this study was Analysis of Variance (ANOVA), and continued with the Least Significant Difference (LSD) test. The results showed that there was an effect of combination feeding on the growth of snakehead fish as indicated by the increase in absolute weight and length. And the sixth treatment is a combination of feed that provides the highest growth in snakehead fish seeds.

Indonesia memiliki peluang bagus guna pengembangan usaha industri budidaya lobster (Panulirus spp.) terbesar di dunia, karena memiliki modal utama ketersediaan sumber daya benih alami stadia puerulus atau Benih Bening Lobster (BBL) yang sangat melimpah. Untuk mengantisipasi perkembangan budidaya lobster di Indonesia, maka kebutuhan akan benih lobster alami di masa mendatang diprediksi akan meningkat secara signifikan, karena teknologi pembenihan lobster belum berkembang. Penelitian ini bertujuan untuk mengkaji produktivitas dan fluktuasi hasil tangkapan BBL pada bulan yang berbeda. Penelitian dilaksanakan pada bulan Maret-Agustus 2022 dengan ditunjang data yang dicatat oleh kelompok nelayan. Lokasi penelitian di perairan pesisir Prigi Kabupaten Trenggalek. Penelitian ini merupakan penelitian deskriptif dengan menggunakan metode survei. Responden dalam penelitian adalah para nelayan penangkap BBL anggota Kelompok Usaha Bersama (KUB) Gurita Jaya. Hasil tangkapan BBL dalam satuan ekor per trip per lembar alat kolektor pocong pada bulan berbeda menunjukkan hasil tangkapan yang berbeda sangat nyata. Puncak hasil tangkapan BBL terjadi pada dua kelompok bulan yaitu pada Maret-April dan Agustus-September. Dalam melakukan penangkapan BBL nelayan Prigi menggunakan kolektor yang dikenal sebagai alat kolektor pocong. Berfluktuasinya tangkapan BBL pada bulan berbeda diduga disebabkan adanya pengaruh fenomena arus, upwelling dan kesuburan perairan di Samudera Indonesia khususnya wilayah perairan pesisir Prigi.Indonesia has the opportunity to develop the world's largest lobster (Panulirus spp.) cultivation industry, because it has the main capital for the availability of abundant natural seed resources at the puerulus stage or Lobster Transparent Seed (LTS). In order to anticipate the development of lobster cultivation in Indonesia, the need for natural lobster seeds in the future is predicted to increase significantly, because lobster hatchery technology has not yet developed. This study aims to examine the productivity and fluctuations in the catch of LTS in different months. The research was conducted in March-August 2022. The research location is in the coastal waters of Prigi, Trenggalek Regency. The research uses descriptive analytical method which is survei. Respondents in the study were fishermen who caught BBL members of the Gurita Jaya Joint Business Group (JBG). LTS catches in units of tails per trip per piece of pocong equipment in different months showed very significant different catches. The peak of LTS catches occurred in two groups of months, namely in March-April and August-September. In catching LTS, Prigi fishermen use a collector known as a pocong fishing gear. The fluctuation of LTS catches in different months is due to the influence of current phenomena, upwelling and water fertility in the Indonesian Ocean and the Prigi coastal waters.
